Beitlgnown that I, JOHN. A. BAUM, a citizenof! the United Sta-tes,Vresiding at Pitts'- bnr-ith inthe ccnintyol Allegheny, and State of Lennsylvania? have invented new. and

useulilmprswmenis ih Ceneri 01" Fiiiflr Securing Devices7V of which thefollowing is areafsaaon.

invention p eIta-insto devices orsecuring articles to walls; ceilings orthe likeVr and relates 'particiilarly to devices lfor,- se-y curingcanopies, brackets or other fixtures.

in; place, @Specially Ornamental Canaries, brackets and fixtures forsupporting Yelectric lamp sockets andthe like.

` -In-secnrlng,V forv instance, in position-'those ornamental canopiesand brackets which are commonly employedzas a snpportvfor electricwalflxltnres, diliicnltyhas been experienced 1n obtaining a sufficientlyfirm connection vwith the wall,v and'it hasbeen aVire-(prienttronblelthat the (canopy has been liablel to when beingdusted or cleanedfthns getting `out o. the correct position and offtenleaving an unsightly mark Aatl the pesitionitVV f ori-ginallyoccupied.Where attempts have y beenniade to, avoid this diii'cult'y andv trouble,they have usually entailed a lessening or they ornamentalqnalites of thecanopy' Itis an object of my invention to produce asecuring4 device for,canopieswall lnackets,v and arti cle-soiy afki'ndred nature, which willybe capable of holdingl thecanopy firmly. in position, so as tovwithstand eiiiciently any strains to which it would be subjected in thecourse of ordinary use' It is another' object ofmy invention to providea securing device which may be operated from' the outside ofthe canopy7or other*.article ,jand which will not in anyway mai: itsappear--v ance.It is a further objectofffmy invention to provide a securing devic'ze'.lwhich Vwill be of a simple and economical nature, and easy to I'iX inplace and to operate. And other and further objects willappear from thefollowing specication, taken in connection with the appended claims.

By way of example, I have described in the following specication andshown in the accompanying drawing7 one form of canopy securing device inwhich my invention may be embodied. I particularly wish it understood,however, that the invention may be embodied in other forms, and thatchanges may be made in the form described and shown, withontk exceeding,the scope thereof,j as defined thev apr iidedf.` clfairrisf ,Fsl''s aninverted plan` ofi aaiiopy piro; e accordance, with Inyfinvetiongwf F1a2f is recibe-.Q11 f linie drawing Y y, Referees@ to the drawing, 1o de11211363 iiffiMl-PYO g'IIiQ imi-Shape" A isfffreqaannyempiyed f1 e obase for l l T i A and the sevraifigur'es of are@ @ligging 1gelectriczwaljiiyiitur. tric iiiture itself'islshodiinfa's 5 extend Yfromthe' canopy, and receive'l the y' nsf ductors, in various. ways which.ariefwll known in theart.V u f .i i y A In c `my,'nveylt.911,Zilli/OGffe: @Classmaifth' Sahcip .l l i'S' hier@ shot/'11,1 provide a,SpPQrl-tta'kmg th-.frm of. acrosspla'te 11, whichextendsffacross theinside of.' the bracken 'and isl'ri'gidlf, secured 'therein by means'oi"solderllZf'Ile erosie'- plate 11 .is formed-with'af'ceiitral liifole ii'rotatably receiving e111' fnteally" Scrvthreaded.V SlyllieV 13 whichfornuis fthe' ,centen Oria womif'wheei 14., f'rna Wenn-w is nellaagarrar-removal faggi.wahnsinnig crossplate llby-,means of Vca -rsA "15,which are stamped out-:from the metal rof the'fcr ssi niet@ asd-bent."eleva ia @were the W0ma-Wnaiv i4, between than' and the badi of thecross-platel" i l Q" The cross-,plate ill, lautern-led with* ont# wardlyextending lugsV v1o''having upr'ifardly- -bent ears 17 which providebearings for a cooperates with the worm-wheel 14; so that 105 i byrotating the spindle 18 the wheel 14 is likewisecausedto rotate.

Such a canopy as is here shown is usually connected to the wall 21 at aplace where an outlet box is provided, the outlet box being usuallyprovided With an outwardly-extending bushing-22. I provide the sleeve 13With V- a plug 23, formed of hard fibre or other insulating composition,Which is secured thereinto and also into the bushing 22 carried in theWall. lt will be seen that by revolving the sleeve 13, by the action'ofthe Worm 2O on the Wheel 14, the canopy 10 can be firmly drawn upagainst the Wall 21. By revolving the sleeve in the opposite directionthe canopy is readily removed.

By the securing device of my invention, which is exceptionally simpleandeconomi- Vvcal' of manufacture, it is possible to draw the canopy, orother article, firmly up against the Wall and secure it immovablythereon.V

It is easyto operate, and further, 4has the special advantage that,being 4entirely Yhidden, except for the small visible end oftheWorm-spindle 18 (which may be made to Vpoint in any direction), it doesnot mar the appearance of the canopy. p

Having thus fully described my invention, what l claim as new, anddesire to secure by Letters Patent is: y

1.l rlhe combination with a fixture of the character set forth, of a.support mounted therein,'a' securing member rotatably mounted in saidsupport, and anactuating member geared to said securing member and ex-VtendingY laterally with respect to theaxis thereof. y

' 2. The combination'witha fixture of the character set forth, of asupport plate extending transversely across the inside thereof andsecured thereto, a'securing member Vrotatably mounted in said plate, andan actuating member gearedV to said securing member and extendinglaterally with respect to the axis thereof.

3. The combination with a fixture of the Vcharacter set forth, of asupport secured therein, a screW-threadedinember rotatably mounted insaid support for cooperation With a corresponding` Wall member, and anactuating member for said threaded member, said actuating member beingrotatably mounted in said support so as to extend laterally Withrespectto the axisof said threadedmember. Y y f W A 4. The combination with afixture ofthe Y WVitnesses :V

character set forth, of a support secured therein, a screw-threadedsleeve rotatably mounted in said support for cooperation with acorresponding Wall member, and an actuating member geared to said sleeveand extending laterally With respect to the axis thereof. Y
